I have some binary_sensors I have created in AppDAemon scripts to assess whether certain appliances are on.
If I open the details about the binary_sensor, I can see that it turns yellow when on (top part of screenshot). But in the card I have, it does not (it’s the one called “dryer” in the card you can see behind, at the bottom of the screenshot):
Edit the card and turn on the toggle “colour icons by state”. It is off by default despite everyone disagreeing with the frontend developers about this.
What a headache, especially since this was a custom:tabbed-card, so I had to find a “standard” card and view in “show code editor” to even figure out what to write in yaml to achieve this (as there’s no UI switch available). Thanks!
